Description

Technical Field

[0001] This invention belongs to the field of satellite telemetry, tracking, and command (TT&C) technology, and specifically relates to a satellite mission planning and scheduling method based on optimal matching. Background Technology

[0002] Satellite telemetry, tracking, and control (TT&C) systems are technical systems that track, measure, monitor, and control the flight trajectory, attitude, and operational status of spacecraft's various subsystems. These systems ensure that spacecraft fly and operate according to pre-designed parameters to complete their designated space missions. Space TT&C systems are an indispensable component of any space system. Whether unmanned or manned, spacecraft must rely on the support of space TT&C systems to enable ground personnel to monitor mission progress, make judgments and decisions, and intervene to achieve operational objectives.

[0003] However, during execution, the algorithm can only perform simple scoring based on time and equipment service duration, and cannot perform satellite telemetry, tracking, and command planning and scheduling in a more scientific manner. Summary of the Invention

[0004] The purpose of this invention is to provide a satellite mission planning and scheduling method based on optimal matching, which overcomes the problem of determining the scheduling scheme based on the service duration of equipment during satellite telemetry, tracking, and command scheduling.

[0005] The technical solution adopted in this invention is a satellite mission planning and scheduling method based on optimal matching, which is implemented according to the following steps:

[0006] Step 1: Compile a list of all usable satellites with access rights, and record the equipment carried by each satellite.

[0007] Step 2: Based on the three-dimensional spatial model, the statistical satellites are divided into orbital layers. In the three-dimensional space, a blank operation layer is established outside each layer. The blank layer selects the airspace without satellites according to the three-dimensional spatial slices to construct the satellite operation model.

[0008] Step 3: Establish the operational orbit on the satellite operational model and input the energy consumption calculation formula for orbit change;

[0009] Step 4: Submit satellite mission application information and permission settings to the satellite operation model;

[0010] Step 5: Select satellites equipped with devices that meet the requirements of the telemetry and control application;

[0011] Step 6: Calculate the energy consumption of orbit change for the selected satellites using the satellite operation model and the orbit change energy consumption calculation formula. Calculate the energy consumption of the satellite changing its orbit from its current orbit to the adjacent empty operating layer. Calculate the energy consumption of the satellite adjusting its direction in the adjacent empty operating layer according to the orbit change energy consumption calculation formula.

[0012] Step 7: Select a low-power satellite and perform orbit change;

[0013] Step 8: After orbit change, the satellite will be tracked and controlled at the applied coordinates within the applied time frame for the applied project.

[0014] Step 2, which involves classifying the satellite orbits based on a three-dimensional spatial model, specifically refers to setting each 100km layer as a reference point on the Earth's surface.

[0015] In step 2, the specific process of slicing the blank layer in three-dimensional space is as follows: with the Earth's center as the center and a step size of 3° cone angle, each layer is sliced.

[0016] Step 4 requires application information including coordinates, time, and project details.

[0017] Step 4, permission settings, includes account registration, level assessment, and classification.

[0018] Permission settings also include priority evaluation and permission evaluation.

[0019] Account registration includes real-name authentication, organization information registration, business scope registration, and organization on-site registration.

[0020] The rating and classification process includes rating application, manual review, and rating confirmation.

[0021] Step 5 is as follows:

[0022] Step 5.1: Select satellites equipped with devices that meet the information requirements of the telemetry and control application project;

[0023] Step 5.2: Select satellites that are available within the application period from the satellites selected in Step 5.1;

[0024] Step 5.3: Filter the satellites that are close to the requested coordinate information in Step 5.2.

[0025] In step 6, the energy consumption for orbit change = energy consumption for lifting and lowering rails + energy consumption for attitude adjustment; the energy consumption for lifting and lowering rails = energy consumption for changes on the operating side + energy consumption for changes in the operating trajectory; and the energy consumption for attitude adjustment = energy consumption for adjusting the equipment orientation + energy consumption for adjusting the flight speed.

[0026] The beneficial effects of this invention are:

[0027] This invention discloses a satellite mission planning and scheduling method based on optimal matching. Through satellite statistics, model building, and orbital information input, a dynamic satellite operation model is established. This model, combined with satellite telemetry and control (TT&C) requests, multiple screenings, and orbit changes, allows for the selection and allocation of satellites with the lowest cost for the applicant to schedule and control. Simultaneously, based on permission settings, request information is prioritized, with higher priority processed first. Furthermore, the TT&C requests are assessed to ensure they fall within the applicant's scope of business, improving the legality of TT&C and preventing out-of-scope TT&C. This results in an optimal matching satellite TT&C planning and scheduling method, while also ensuring the legality of TT&C operations. Attached Figure Description

[0030] This invention provides a satellite mission planning and scheduling method based on optimal matching, such as... Figure 1 As shown, please follow these steps:

[0031] Step 1: Compile a list of all usable satellites with access rights, and record the equipment carried by each satellite.

[0032] Step 2: Based on the statistical analysis of satellites in three-dimensional space model, with the Earth's surface as the reference, set 100km as a layer to perform orbital layering. In three-dimensional space, and outside each layer, establish a blank operation layer. For the blank layer, in three-dimensional space, with the Earth's center as the center and a 3° cone angle as the step size, slice each layer, select the airspace without satellites, and construct the satellite operation model.

[0033] Step 3: Establish the operational orbit on the satellite operational model and input the energy consumption calculation formula for orbit change;

[0034] Step 4: Submit satellite mission application information and permission settings to the satellite operation model;

[0035] The application information includes coordinates, time, and project information.

[0036] Permission settings also include priority assessment and permission assessment;

[0037] Account registration includes real-name authentication, organization information registration, business scope registration, and organization on-site registration.

[0038] The rating and classification process includes rating application, manual review, and rating confirmation.

[0039] By confirming the priority of registered users through the steps of application, manual review, and confirmation, priority can be given to satellite tracking, telemetry, and command (TT&C) planning and scheduling. At the same time, the coordinates of the tracking, telemetry, and command planning of an organization can be identified through the registration of organization information, business scope, and organization's on-site registration to determine whether they fall within the organization's permitted operating range, thus avoiding illegal and disputed situations caused by tracking and command exceeding authority.

[0040] Step 5: Select satellites equipped with devices that meet the requirements of the telemetry, tracking, and command application; the specific process is as follows:

[0041] Step 5.1: Select satellites equipped with devices that meet the information requirements of the telemetry and control application project;

[0042] Step 5.2: Select satellites that are available within the application period from the satellites selected in Step 5.1;

[0043] Step 5.3: Filter the satellites that are close to the requested coordinate information in Step 5.2.

[0044] Step 6: Calculate the energy consumption of orbit change for the selected satellites using the satellite operation model and the orbit change energy consumption calculation formula. Calculate the energy consumption of the satellite changing its orbit from its current orbit to the adjacent empty operating layer. Calculate the energy consumption of the satellite adjusting its direction in the adjacent empty operating layer according to the orbit change energy consumption calculation formula.

[0045] Energy consumption for track change = energy consumption for lifting and lowering rails + energy consumption for attitude adjustment; energy consumption for lifting and lowering rails = energy consumption for changes in the operating side + energy consumption for changes in the operating trajectory; energy consumption for attitude adjustment = energy consumption for adjusting the equipment's orientation + energy consumption for adjusting the flight speed.

[0046] Step 7: Select a low-power satellite and perform orbit change;

[0047] Step 8: After orbit change, the satellite will be tracked and controlled at the applied coordinates within the applied time frame for the applied project.

[0048] The working principle of the satellite mission planning and scheduling method based on optimal matching in this invention is as follows:

[0049] By using satellite statistics, model building, and orbital information input, a dynamic satellite operation model is established. This model, combined with satellite telemetry and control (TT&C) requests, multiple screenings, and orbit changes, allows for the selection and allocation of satellites with the lowest cost for the applicant to schedule and control. Simultaneously, based on access permissions, request information is prioritized, with higher-priority requests processed first. Furthermore, the TT&C requests are assessed to ensure they fall within the applicant's scope of business, enhancing the legality of TT&C and preventing overreach. This results in an optimally matched satellite TT&C planning and scheduling method, while also ensuring the legality of TT&C operations is controlled.

[0050] Example:

[0051] First, log in to your account, submit a satellite tracking and control application, and submit the application information to the satellite operation model. Determine if the application falls within the registered work scope, and queue the satellites according to priority. Wait for satellite allocation, select satellites equipped with equipment that meets the requirements of the tracking and control application, select satellites that are available within the application time, and select satellites with adjacent application coordinate information. Using the satellite operation model and the orbit change energy consumption calculation formula, calculate the orbit change energy consumption of the remaining satellites after the screening (three screening steps in step 5). Calculate the energy consumption of the satellite changing its orbit from its current orbit to an adjacent empty operating layer, and also calculate the energy consumption of the satellite turning and adjusting its position in the adjacent empty operating layer. Select the satellite with the lowest energy consumption, perform the orbit change, and wait for the satellite to pass through the application coordinates within the application time for tracking and control of the application project, thus completing the satellite tracking and control planning and scheduling.
